1. An orbital propulsion system comprising:
a payload assembly;
a pair of propellable masses couplable to the payload assembly and cyclically moveable in diverging and converging directions in relation to each other, wherein a mass of a first of the propellable masses is different to a mass of a second of the propellable masses;
a binding mechanism configured to physically constrain the pair of propellable masses;
a mass directing mechanism configured to control an attitudinal orientation of the propellable masses; and
a control system configured to:
alter a spatial mass distribution of the propellable masses to reduce a gravitational deviation of a trajectory of the payload assembly for providing a resultant propulsive force to the payload assembly;
accelerate the propellable masses in directions toward an outer extent of the binding mechanism, respectively, wherein the directions being angled with a gravitational field of a gravitational body, and to positionally direct the propellable masses to determined first positions or first regions that reduce the gravitational deviation of the trajectory of the payload assembly; and
accelerate the propellable masses in directions toward an inner extent of the binding mechanism to increase the gravitational deviation of the trajectory of the payload assembly for restoring an initial state of the payload assembly that experiences increased gravitational deviation or to create a state of increased gravitational deviation, and to positionally direct the propellable masses to determined second positions or second regions that increase the gravitational deviation of the trajectory of the payload assembly;
wherein each of the propellable masses being propelled by a propellant to accelerate the propellable masses toward the outer extent of the binding mechanism;
wherein a payload being contained in any one of or any combination of the payload assembly, and the propellable masses.
